Dyson’s Pressed Alumina Crucibles – Product Range

ISO-Alumina A97
Iso-pressed and high fired Alumina offers very good abrasion resistance. Often used in the melting of Basic Carbon Steel and its alloys, Palladium and Stainless Steel.

ISO-Alumina Mullite AM88
Iso-pressed and high Fired, offering good abrasion resistance and enhanced thermal shock resistance when compared to high Alumina. Used in the melting of basic carbon steels, where thermal stress is an issue

Introducing: ISO-AZ76 Zirconia enriched Alumina.
Bridging the gap between Alumina and Zirconia, AZ76 offers superior erosion resistance to high Alumina and an economical alternative to Zirconia. In addition to this, AZ76 is also being used as a replacement to Chrome Alumina, avoiding the Health and safety as well as the environmental issues with that material. ISO-AZ76 offers a diverse range of applications, which include:

Glass

Basic Carbon steel and its alloys

Alloy Steels

Nickel and Colbalt based Superalloys.

Dyson's Crucible Sizes

Below is a list of common crucible sizes. Please note that the sizes are accurate for our "ISO Zirconia M" composition. Crucible sizes will vary depending on composition choice, due to shrinkage during sintering. While all zirconia crucibles are similar in size, Alumina crucible may be up to 3.5% larger than the dimensions quoted below.

Dyson Technical Ceramics™ manufactures a wide range of high performance pressed Zirconia Crucibles, based upon partially stabilised Zirconia. Zirconia Crucibles are often used in the precious metals, aerospace and biomedical industries. Applications include the investment casting of Nickel, Cobalt and Chrome containing alloys, along with high temperature melting and refining of Platinum Group Metals (PGMs’).

Dyson Technical Ceramics manufactures a comprehensive range of high performance Zirconia Tundish Metering Nozzles used mainly in the continuous casting of steel billets. Tundish Nozzles usually comprise a zirconia inner nozzle (often referred to as a “zirconia insert”) with a lower grade outer body such as Alumina, Zircon or Bauxite.

For more detailed information please see below or alternatively, download one of our brochures.

Dyson Technical Ceramics™ Zirconia Ceramics Filters are used in the filtration of Steel and Nickel/Cobalt based superalloy castings. DysonTC’s Zirconia Ceramic Filters offer resistance to high temperatures, while maintaining excellent erosion resistance. The fine textures of the filters provide excellent filtration properties, giving the caster cleaner melts and reducing the need for grinding/machining. Advanced production techniques help to give the filters an even 3D lattice, resulting in a smooth, non-turbulent melt flow.

Complimenting Dyson’s range of crucibles Dyson Technical Ceramics also offer thermal insulating Dypack™ backing material, which can be used in air and induction melting applications. Also referred to as “Ramming Material” or “Crucible Back-up”, it creates a safety barrier in the unlikely event of a crucible failure. The crucible back-up also insulates the crucible, helping reduce changes in temperature that can cause thermal stress.

Incorporating low iron, pre-calcined dense grain materials, this product is formulated to provide high strength, high abrasion resistance, low porosity and high refractoriness combined with a high resistance to glass furnace carryover, vapours and solids.

SDR-F

A dry pressed high strength abrasion resistant firebrick with good dimensional tolerance. SDR-F is a high performance firebrick which finds application where resistance to glass furnace carryover in solid or vapour forms is required.

Dyson Technical Ceramics™ STANNEX™ electrodes are made from ultra-high purity Tin Oxide, and are an advanced alternative to traditional Molybdenum electrodes.

Carefully selected additives are used to promote good sintering and give a dense product with exceptional electrical conductivity and refractory properties. The use of Tin Oxide also helps avoid the discolouring that can sometimes occur with Molybdenum electrodes.

All STANNEX™ electrodes are isostatically pressed and contain no recycled or reclaimed material to ensure superb consistency and the high quality production. Every electrode is individually tested and approved before dispatch.

Dyson Technical Ceramics manufactures a range of high density zirconia sliding gate plate inserts, which are used within sliding gate plate applications. The inserts are generally used within a cast or pressed refractory plate.

Sliding Gate Plate inserts are an excellent solution to increasing the life span of sliding gate plates. Once a sliding gate plate becomes worn,
the worn material can be removed and a high density DysonTC Zirconia Plate insert can be cemented/cast in its place, therefore extending the life of the sliding gate plate.

Dyson Technical Ceramics™ Foundry Ladle Nozzles are available in a range of Alumina grade material qualities to suit casting requirements. Our nozzles are made from high purity raw materials to promote higher erosion resistance to metals and alloys.

A combination of excellent cosmetic appearance and dimensional accuracy promotes stable casting conditions. All our nozzles are available in a wide variety of bore sizes and are widely used in bottom pour ladle applications, where flow control is of paramount importance. Our efficient manufacturing techniques enable our clients to get the products they need, when they are needed.
